(54)	Audible signal encoding method

(57) A method for encoding an audible signal in which an input audible signal is represented by parameters derived from an input audible signal converted into a frequency-domain signal, and the input audible signal, thus represented, is encoded, wherein, for weighted vector quantization of said parameters, the weight is calculated based on the results of orthogonal transform of parameters derived from an impulse response of a weight transfer function.
